... There is a communication problem due to a bug in the microcontroller mounted on the self-check board when the QB-78K0MINI operates on the Ring-OSC. The debugger takes a measure to avoid this problem by forcibly switching to the main clock when a break occurs, and re-switches to the Ring-OSC when the program is executed. Consequently, the QB-78K0MINI always operates on the main clock during a break. • ...
